CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 650,993, dated June 5, 1900.

App ion filed February 4, 1899. Serial No. 704,472. (No model.)

To (tZZ whom, it may concern.-

Be it known that I,.CLARK W. SHARRoW, acitizen of the United States of America, and a resident of Philadelphia, county of Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Cash-Registers, of which the following is a specification.

My invention has reference to cash-registers and it consists of features fully set forth in the following specification and accompanying drawings, forming part thereof.

The object of my invention is to provide, first, an indicator mechanism for a cash-register of an extremely-simple character, and, secondly, a registering mechanism of novel design, both of which are cheap to construct and efficient in their Work.

It consists of a series of tablet-rods in combination with a series of keys, one rod for each key and tablet-rod being provided with an integral detent adapted to engage with a common rod-supporting Wing or lock. Each rod in addition to the detent aforementioned carries a pivoted pawl, which pawl performs the function of swinging the wing on its carrying-rod, being raised by the operating-key therefor. The oscillation of the wing by any one of the pawls will release any one of the previously-raised rods supported by the wing, and thus permit any one of the previouslyraised rods to drop. I thus dispense with all common intermediate connections between the operating-key and the wing or supportinglock for the tablet-rods and make each rod the element for releasing any or all of the others of the series.

A second feature of my invention is a registering mechanism comprising aband for each key,preferably of steel or some other inelastic substance, and means connected with the respective key of each band for actuating it.

In the drawings like parts are referred to by letters of a corresponding kind in the different views.

Figure l is a transverse vertical section through the machine and showing one of the keys and its corresponding indicating-rod. Fig. 2 is a front View of the tablet-locks with the registering mechanism and case removed. Fig. 3 is a section on line C C, with case and tablet mechanism removed, showing merely the registering-bands. I

A is a cabinet inclosing the mechanism of the machine.

B is the common key-supporting rod, and C is the key supported thereby.

e e are two guides for the tablet-rods, and D is one of the tablet-rods. It will of course be understood that there is one rod for each key, as is usual in machines of this class.

F is an enlarged detent carried by the tablet-rod D and integral therewith.

All rods and keys being exactly alike, I will limit my description to but one series.

f is the indicator, carried by the rod D at its upper extremity.

G is an oscillating pawl carried by the rod D, and J is a pawl-arresting pin on this rod whereby the pawl is maintained in proper working position.

F is a common tablet lock or wing and is adapted to be operated by any one of the said rods in the manner to be described.

a is a spring carried by the wing I and holds the said wing normally in contact with the pin 71, the said pin being carried by the standard of the machine. The glass through which the tablet can be viewed is shown 'at f From the foregoing description of the structure of my indicator mechanism it is evident the operation is as follows: As the key 0. is oscillated the tablet-rod D is raised. In its upward movement the pawl G contacts with the wing I and swings it far enough to permit any rod-detent F to be disengaged therefrom, whereupon all previously raised and supported tablet-rods so disengaged will drop and return to their normal position of rest on their respective keys. The spring e immediately on the disengagement of the pawl G from the wing will snap the wing against the pin h, and as the wing will then be in the downward path of the detent I it will arrest the tablet and hold it up. It .is hardly necessary to note that one of the tablet-rods D is shown as raised and one as down in Fig. 1. B is one of a series of registering-bands. There is one band for each key.

N is a common supporting-rod for the individual winding-reels n of the bands.

XV is a receiving-reel for one of the aforementioned bands. tis a common supportingrod for these individual reels.

R is a pawl for actuating the ratchet V of the reels W.

S is a pivot retaining the pawl R to the depending arm L of the key 0.

O is a pawl carried by the key 0 and actuates the ratchet L and its disk L. (Best shown in Fig. 3.)

I have now described the structure of my registering mechanism. It remains yet to explain its operation, which is as follows: On the operation of the key 0 the pawl O is raised, and thereby operates the ratchet c. This ratchet actuates a rigid metallic drum L (Best shown in Fig. 3.) m, Fig. 1, is a coinciding drum. These two drums form a band-feed, as is evident. Therefore on each operation of the key 0 the ratchet L is actuated. Thereby the drum L and registeringband B are moved forward, in practice, to the pitch of the numerals on the face of the band or tape. The depending arm L, carrying the pawl R, actuates the take-up drum V simultaneously with the operation of the paperfeeds L and m.

It is hardly necessary to remark that the mechanism described is duplicated for each key.

I do not show any resetting mechanism in this present application, and for the purposes of this case we will assume that the bands are to be reset by hand individually.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a cash-register, the combination of a series of tablet-rods each having a detent thereon, a plate so pivoted that its upper edge may rest under said detent to support said rod, a pawl pivoted on the rod in proximity to said detent with its edge extending beyond the edge of the detent and a stop on the rod for arresting the motion of said pawl in a position in advance of the detent whereby as the rod is raised said pawl is brought against the upper edge of the plate to move the same substantially as described.
